Journal of Neurologic Physical Therapy -- 2015, v. 39, 2, p. 127-133Summary: Background and Purpose: Body-weight–supported treadmill training has been shown to be an effective intervention to improve walking characteristics for individuals who have experienced a stroke.
A pressure-controlled treadmill utilizes a sealed chamber in which air pressure can be altered in a controlled manner to counteract the effects of gravity. The focus of this case study was to assess the immediate and short-term impact of a pressure-controlled treadmill to improve gait parameters, reduce fall risk, improve participation, and reduce the self-perceived negative impact of stroke in an individual with chronic stroke.
Case Description: The subject was an 81-year-old man (14.5 months poststroke). He had slow walking speed, poor endurance, and multiple gait deviations.
Intervention: The subject trained 4 times per week for 4 weeks (40 minutes per session) on a pressure-controlled treadmill (AlterG
M320) to counter the influence of gravity on the lower extremities.
Outcomes: Following training, self-selected gait speed increased from 0.50 m/s to 0.96 m/s, as measured by the 10-meter walk test.
Stride length increased from 0.58 m to 0.95 m after training and to 1.00 m at 1-month follow-up. Peak hip flexion increased from 3.7◦ to 24.6◦ after training and to 19.4◦ at 1-month follow-up. Peak knee flexion increased from 19.4◦ to 34.3◦ after training and to 42.7◦ at 1-month follow-up. Measures of endurance, fall risk, and percentage of perceived recovery also were found to improve posttraining.
Discussion: Training with a pressure-controlled treadmill may be a viable alternative to traditional body-weight-supported treadmil training for persons poststroke. Additional studies with larger sample sizes are needed to elucidate the role of pressure-controlled treadmill training in this population.
